It Is More Important To Have Beauty In One's Equations Than To Have Them Fit Experiment... It Seems That If One Is Working From The Point Of View Of Getting Beauty In One's Equations, And If One Has Really A Sound Insight, One Is On A Sure Line Of Progress. If There Is Not Complete Agreement Between The Results Of One's Work And Experiment, One Should Not Allow Oneself To Be Too Discouraged, Because The Discrepancy May Well Be Due To Minor Features That Are Not Properly Taken Into Account And That Will Get Cleared Up With Further Developments Of The Theory.

Renormalization Is Just A Stop-gap Procedure. There Must Be Some Fundamental Change In Our Ideas, Probably A Change Just As Fundamental As The Passage From Bohr's Orbit Theory To Quantum Mechanics. When You Get A Number Turning Out To Be Infinite Which Ought To Be Finite, You Should Admit That There Is Something Wrong With Your Equations, And Not Hope That You Can Get A Good Theory Just By Doctoring Up That Number.

If We Are Honest - And Scientists Have To Be - We Must Admit That Religion Is A Jumble Of False Assertions, With No Basis In Reality.

Hopes Are Always Accompanied By Fears, And, In Scientific Research, The Fears Are Liable To Become Dominant.

A Termination Of One's Life Is Necessary In The Scheme Of Things To Provide A Logical Reason For Unselfishness. . . . The Fact That There Is An End To One's Life Compels One To Take An Interest In Things That Will Continue To Live After One Is Dead.
